To all whom it may concern:

Be 1t known that I, FREDERICK E. GOLD- SMITH, a cltl zen of the United States, residing at Middletown, in the county of Butler and to be continuously stirred or agitated to prevent the settling of heavier constituent-s, to

keep the mixture in a fiuid state, or for other reasons.

My invention provides a suitable agitator and further adapts the agitator for use in connection with a machine which has a r0- tary drum or similar device for elevating the coating material to the point where it is applied to the tile or to the device which is emtion that it hardens.

ployed for directly applying the material to the tile.

A further object of my invention is to construct and arrange the agitator in relation to other parts of the machine sothat it may readily be brought to an accessible position for cleaning with a minimum of disturbance to other parts of the machine.

Another object is to 'rovide a cushioning or yielding connection etween the agitator and the device which drives it. This is desirable because if the coating process is discontinued for any considerable time with coating material remaining in its receptacle, the material is generally of such a composi- On re-commencing coating and agitating the material, therefore, the agitator is embedded inor encounters a quite solid mass of material which would, ifa rigid driving connection were provided, cause damage or breakage of either the agitator or its driving mechanism, or some other related art.

A still further object is to provide a ready means for connecting and disconnecting the agitator with its driving member to facilitate moving the agitator to the cleaning position.

The accompanying drawing illustrates exemplifying structures embodying the invention.

In the drawingsFigure 1, is a vertical my invention; Fig. 2, a plan view of the, tub, drum, and agitator; Fig. 3, a detail view of the yielding driving connection; Fig. 4, another view of the driving connection in o erative position ;.and Fig. 5, anenlarged etail of the pitman connection.

A suitable frame 1 supports at its top the longitudinal section of a machineeinbodying coating device or devices pro er which in the present instance are exempli ed by a coating roll 2 although any other of many different forms of coating devices may be employed.

Feed and delivery aprons 3, 4 are provided for supplying tile to and removing them from the coating device, respectively.

Other essential features of a coating machine suchias driving mechanism etc. of any suitable construction are to be assumed.

Below the coating device and conveniently supported within the frame is a tub 5 const tuting a coating receptacle. suitable bearings conveniently in the frame and passing through the side walls of the tub is a shaft 6 carrying a rotary drum ,or other coating elevating device 7. Two short agitator shafts 8 are revolubly mounted conveniently in bearin s in the frame preferabl above shaft 6 an pass through the side wa of the tub. Arms 9 are connected with or formed continuous with the inner ends of the shafts S and are curved laterally and downwardly, as shown, so as to avoid shaft 6 and yet permit turning of shafts 8 through a considerable are without the arms encountering the shaft 6. The agitator proper is designated in general by numeral 10 and may consist, as in the exemplification shown, of a grid having cross-bars 11 extending across the tub near the bottom and connected to end pieces 12 which are in turn connected to the ends of arms 9. The bottom of the tub, as 211313, is preferably curved on an arc struck from the center of shafts 8, and the grid 11 conforms to this curvature and lies between the drum 7 and the bottom of the tub and close to the latter.

By reason of the curvature of arms 9 and the arrangement of the sup orting shafts for the agitator in relation to t at of the drum, the agitator may swing back and forth in a wide are as shown by the dotted lines without interfering with other parts, thoroughly stirring the coating material in the tub and Mounted in v particularly agitating it nearest the bottom of the tub Where the heavier constituents of the material most'tend to accumulate.

By swinging the agitator to the left, as seen in Fig. 1 it may be brought up above the drum and near the coating device where it is readily accessible for cleaning. For this purpose a ron 3 and other parts which may normally 'e across the upper part of the frame may be hinged or otherwise arranged to be swung out of the way or entirely removed while the agitator is being cleaned.

To the outer endof one of the agitator shafts 8 is connected a crank arm 14 whichcarri'es a pin 15 -on which ismounted revolubly a s 001 or thimble 16 Suitably mounted ont e frame is a driving-shaft 17 which may or may not im elother parts of the coating machine an the agitator. This shaft carries a crank pin 18.

' Numeral 19 designates in general a pitman connecting crank pin 18 and crank arm 14.

, tothe cleaning position it is desirable to pro- Thimble 16 has connected to it in amanner which will later be described a longitudinally bored handle 20. Through the bore of handle 20 runs a main or center rod 25 carrying at one end beyond the handle a nut 26 serving as a stop, and connected at the other end to an operativel integral head 22. Crank in 18 carries a b ock 22 through which pass 'stance rods 23 carrying stop nuts 24 beyond the block and secured at the r other ends to a block 21 which is centrally bored so as to slide upon center rod -25. Distance rods 23 also pass through holes provided for the urpose in head 22. Between heads 21 an 22,

' surrounding the center rod, is a helical comhand end, asseen in Fig. 3, and block 22? pression s ring 27. Under ordinary 'conditions, wh' e the machine is in operation, pitman 19 acts in an ordinary manner to oscilspring 27 is compressed between heads 21 and 22 more or less depending upon the resistance of the agitator to movement; when this compression occurs center rod 25 slides through the handle and projects at the left and head 22 slide upon distance rods -23 i which project at the right hand end of the block. The compression of the spring of course varies with the resistance of the a itator and in some cases if the agitator is eld stationary the crank pin will make a full revolution without moving the agitator but only compressing the spring. When crank pin 18 moves away from the center of the machine the spring still acts under compression to urge the agitator to move in the correspdnding direction before the parts assume the position shown in Fig. 4.' That is, block 22 engages thestop nuts Men the ends of the distance rods, head 21 is moved away from handle 20 and slides on the center rod, and stop nut 26 on the end of the center rod comes up against the end of the handle. The spring is now compressed as before between heads 21 and 22. As rotation of shaft 17 continues alternately urging the agitator in opposite directions the coating material becomes gradually loosened and the agitator is ermittedto move correspondingly until ally the mass is entirely loosened and the agitator movesin a normal manner, with the spring extended and holding the parts; in normal running) position.

To permit the agitator to e readily moved vide ready means of disconnecting the pitman from crank arm 14. Such a device is shown in Figs. 4 and 5. Handle 20 is provided with projections 28, 29 which emto it and having a fin er 32 entering a recess in latch 30. Thelatc lever is held outward from the handle and the latchthereby held in normal osition by means of a coiled spring carried in iousing 33 in the latch lever. To disengage the pitman, the latch lever is moved toward the handle Withdrawing the latch from engagement with the thimble and permitting the handle to be lowered away from the thimble. The agitator can then be swung .up to cleaning position in the manner before described.

The structures shown as embodiments of my invention are only exemplifications and I contemplate many and wide alterations therein within'the scope of the invention.

1.- In a machine for coating, the combination of a coating receptacle, a liftin drum, an agitator, and means for impellmg the agitator.

2. In a machine for coating, the combination of a coating receptacle, a rotary drum for elevating coatin material, an agitator, and means for impel ing the agitator.
